dc.description.abstract | The impact of human activity on the sediments of Todos os Santos Bay in Brazil was evaluated by elemental
analysis and 13C Nuclear Magnetic Resonance (13C NMR). This article reports a study of six sediment
cores collected at different depths and regions of Todos os Santos Bay. The elemental profiles of cores collected
on the eastern side of Frades Island suggest an abrupt change in the sedimentation regime. Autoregressive
Integrated Moving Average (ARIMA) analysis corroborates this result. The range of depths of
the cores corresponds to about 50 years ago, coinciding with the implantation of major onshore industrial
projects in the region. Principal Component Analysis of the 13C NMR spectra clearly differentiates sediment
samples closer to the Subaé estuary, which have high contents of terrestrial organic matter, from
those closer to a local oil refinery. The results presented in this article illustrate several important aspects
of environmental impact of human activity on this bay. | pt_BR |
